Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is, for example, connected between a supply system such as an oil tank in an automobile or the like and a combustion system such as an engine. The present invention relates to improvement of a fuel oil reformer used for the purpose.

[0002]

2. Description of the Related Art Generally, in fuel oil fed from a fuel supply system such as an oil tank to a combustion system such as an engine, oil molecules are bound to each other as particles having a particle size of about 0.45 μm to 0.6 μm. The so-called unprocessed fuel oil in the ready state is used. Since this untreated fuel oil has a large particle size and a small contact area with air, if it is used as it is in a combustion system, incomplete combustion will occur and combustion efficiency will decrease, leading to an increase in fuel consumption. There is. Further, a decrease in combustion efficiency also causes an increase in exhaust smoke concentration, and it has been pointed out that the particulate matter in the exhaust smoke adversely affects the human body and is regarded as a problem. In addition, hydrocarbons (HC), nitrogen oxides (NO
This results in a large amount of harmful substances such as x).

In order to solve the above problems, conventionally, magnetism is applied to fuel oil to separate mutual coupling of oil molecules constituting the fuel oil to atomize the oil particles to burn the fuel oil with high combustion efficiency. There are widespread attempts to obtain equipment for feeding the system. As one of such attempts, the present inventor
Already, Japanese Patent Application No. 5-56470 (JP-A-6-24827)
No. 7) feeding fuel oil reformer (conventional device) is proposed.

In this conventional apparatus, an oil inlet / outlet is communicated with a cylinder core in a cylindrical casing 1 having an oil inlet (not shown) at one end and an oil outlet (not shown) at the other end. An oil passage pipe 2 is provided, and a plurality of annular permanent magnets 3 are provided in the oil passage pipe 2.
In a repulsive relationship with each other, the magnetic field line integrating yoke 4 is interposed between the adjacent magnets, and the magnets are closely contacted with each other.
A plurality of sets of G2 and G3 are fitted and fixed in a suction relationship via a spacer 5, and a magnetic field enhancing shaft is arranged in the oil passage pipe 2.

The repulsive magnetic field generated by the annular permanent magnet 3 having a repulsive mutual close configuration and the magnets G1 and G2 having an attraction relation.
When a magnetic field that is complicated with the adsorption magnetic field generated between the G3s is amplified and created in the oil passage pipe 2 by the cooperation of the magnetic field line integrating yoke 4 and the magnetic field enhancement shaft 6, and the fuel oil is passed through the oil passage pipe 2. In this method, an amplified complex magnetic field is applied to the fuel oil to atomize the oil particles of the fuel oil to feed the reformed fuel oil to the combustion system.

[0006]

By the way, since the annular permanent magnet 3 used in the above-mentioned conventional device has one surface having an N pole and the other surface having an S pole, a magnetic force corresponding to the magnetic flux density is generated at both surface portions. However, the magnetic force generated on the inner peripheral surface is extremely weak. Therefore, the above-mentioned structure is adopted in order to generate a corresponding magnetic force on the inner peripheral surface side and cause the magnetic force to act on the fuel oil in the oil passage pipe.

However, the repulsive magnetic field generated on the inner peripheral side between the plurality of annular permanent magnets 3 closely contacted to each other in a repulsive relationship is not supplemented by the magnetic field line integrating yokes 4 interposed between adjacent ones, and Even if the magnetic field enhancing shaft 6 in the oil passage pipe 2 enhances the magnetic field, there is a limit in exerting a repulsive magnetic field in the oil passage pipe 2 according to the magnetic flux density of both sides of the annular permanent magnet 3. Was there. As a result, in the above-mentioned conventional device, although the combustion efficiency is improved and the exhaust smoke concentration is reduced as compared with the case where untreated fuel oil is supplied to the combustion system, it is possible to obtain a satisfactory effect. The current situation is not. Further, in the conventional apparatus, a large number of annular permanent magnets 3 are assembled in a repulsive relationship to form the assembled magnets G1, G2, G3, and the assembled magnets are arranged in an attractive relationship via the spacer 5, so that the assembly workability is extremely poor and the magnetic force lines are It also required extra parts such as the integrated yoke 4 and the magnetic field enhancement shaft 6.

The present invention has been made in view of the above circumstances, and makes full use of the inherent performance of a permanent magnet to constantly produce an effective magnetic field corresponding to the magnetic flux density in the oil passage pipe. It acts on the passing fuel oil to accelerate the atomization of oil particles, improve the combustion efficiency, increase the power of the combustion system, reduce the fuel consumption, reduce the smoke concentration and carbon monoxide or hydrocarbons, and prevent pollution. The object of the present invention is to solve the contradictory requirements of the above all at once, to facilitate the assembling work, and to reduce the number of parts to be assembled.

[0009]

The present inventor felt the limit of using an annular permanent magnet to create a sufficient magnetic field in the oil passage pipe, and was searching from various points of view. It has been found that a sufficient magnetic field according to the magnetic flux density can be exerted in the oil passage pipe by closely adhering at least a pair of magnetized roof tile-shaped permanent magnets in an adsorption relationship around the oil passage pipe, and completed the present invention. Came to let.

That is, according to the present invention, a magnetic oil passage pipe for connecting the oil inlet and the oil outlet to a cylinder core in a cylindrical casing having an oil inlet for fuel oil at one end and an oil outlet at the other end. Around the oil passage pipe, an N-pole roof tile permanent magnet having an N-pole on the inner peripheral surface side and an S-pole having an S-pole on the inner peripheral surface side.
At least one pair of pole-shaped tile-shaped permanent magnets are closely adhered to each other so as to face each other in an inner surface attraction relationship, and when fuel oil is passed through the oil passage pipe, it is formed between the N-pole and S-pole-shaped tile-shaped permanent magnets. The adsorption magnetic field is applied to the fuel oil to atomize the oil particles of the fuel oil.

[0011]

The oil passage pipe is magnetized by the S-pole tile-shaped permanent magnets and the N-pole tile-shaped permanent magnets which are attached around the oil passage pipe. A sufficient adsorption magnetic field is created according to the magnetic flux density of. When the fuel oil passes through the oil passage pipe, it comes into contact with a strong and stable adsorption magnetic field, is efficiently subjected to a sufficient magnetizing action, atomizes the oil particles, and improves the reaction efficiency with air. , Will be delivered to the combustion system. Therefore, in the combustion system, complete combustion at a low combustion temperature is realized, combustion efficiency is improved, and fuel consumption is reduced. Further, since the generation of exhaust smoke is also suppressed, harmful particulate matter in the exhaust smoke is reduced, and nitrogen oxides, carbon monoxide, hydrocarbons, etc. in the exhaust gas are also reduced.

The adsorption magnetic field is created uniformly and strongly in the oil passage pipe 20. Originally, the oil particles of unprocessed fuel oil are aggregates of the oil molecules that compose the untreated fuel oil, and when they are affected by a strong adsorption magnetic field, they become magnetically excited. Become. As a result, this excitation energy divides the binding force between the oil molecules, and the oil molecules move in the direction according to their magnetism, whereby the oil particles are atomized while separating into small particles. Then, by repeating the above-described action, the particle size of the oil particles is 0.45 μm to 0.6 μm before the treatment,
The particles are atomized from 5 μm to about 0.3 μm, the reaction efficiency with air is increased, and then the particles are sent to the combustion system 16. In the combustion system 16, since the reformed fuel oil is easily atomized and dispersed, the combustion can be performed at a low combustion temperature, and the combustion close to the complete combustion can be obtained. Therefore, combustion efficiency is improved and fuel consumption is reduced. At the same time, the exhaust smoke concentration is suppressed, and particulate matter, carbon monoxide, hydrocarbons, nitrogen oxides, etc. in the exhaust smoke are also reduced.
